IMPROVEMENT IN HOLDBACK ATTACHMENTS FOR HAMES.

Specification forming part of Letters Patent No. 188,955, dated March27, 1877 application tiled February 2l, 1877.

To all'whom it may concern Be it known that 1, JULIUs RoBBINs, ofAuburn. in the county of Cayuga and State of New York, have inventedcertain new and useful Improvements in Holdback Attachments for Hannes,of which the following is a specification In the manufacture of thewooden hames in use prior to my invention, it was customary to mortisethrough the side of the haine for the loop which receives the tug-clip,and also to mortise for the holdback-staple through the front side ofthe haines, which method of construction very frequently caused thehames to he broken, and was a serious element of weakness. It was alsothe invariable custom to rigidly attach the shank of the breast-chainring or holdback-staple, which was apt to cause the chain to twist az.dto jar the connections, especially should ruts cause the pole to bethrown suddenly out of its usual position.

In the accompanying drawings, Figure 1 represents a perspective of awooden haine embracing my invention; Fig. 2, a view of the holdbackattachment brace-plate before being applied thereto; Fig. 3, a View ofthe heye or swivel staple, which is rst forged or cast and its socketcast around it, as will be described, and Fig. 4 a cross-section throughthe holdback attachment as applied.

The brace-plate A is cast of malleable metal or brass, and has threeprongs, a a a', and are about equi-distant trangularly from their ends,and when applied to the face of the hame these ends are upset to graspits under side, and the plate when applied is thus prevented frommoving. The plate A is further secured by rivets b through the llame.EX- tending from the end a', and cast with the plate, is the tug-loop c,to receive the clip of the tug. The staple or swivel socket d is fiaringon its under side at dl, I'or a purpose to be presently described, whileon its upper or face side it has an elevated socket-bearing, d2, forsaid swivel.

The swivel-staple B is forged or made separately, and has an eye, e, anda web-shank, f, around which, according to a well-known process ofmanufacture, the socket-bearing of the brace-plate is cast, and thestaple B swivels freely therein. In this eye e the holdbackring U iswelded.

The shank f rests flush upon the surface of the hannes, and swivelingfreely prevents the twisting of the breast-chain or breaking of thebreast-strap When used, and also avoids the jarring and liability tobreak incident to a rigid connection. This joint being universal, theplay of the holdback-ring is accommodated to every draft of the'breast-chain from whatever position or source.

The three ends a a a being triangular, and and bent over and under inthe curve line of the haines, prevent the plate from moving, and bracethe llames at this point. This device can be applied to any haines.

I claim- 1. The combination, with a haine, of a swiveling holdbackring.

2. Ihe combination of a swiveling holdbackring with a brace-plate, inwhich it is socketed.

3. The brace-plate A of a holdback attachment, provided with an elevatedhearingsocket, d2. in combination with a swivelingeye, B, provided withawebshank,f, as and for the purpose described.

4. The brace-plate A of a holdback attachment, provided with thetriangular bracingends a a a', substantially as described.

5. A brace-plate for a hames holdback attachment, consisting of thetriangular bracing-arms, the tug-loop for the clip, and an elevatedsocket-bearing, having an inward and an outward iiare, in colnbinationwith a swiveling holdback adapted thereto, substantially as described.

In testimony whereof` I have hereunto set my hand in the presence of twosubscribing witnesses.
